BHL™ Cryotanks

BHL™ Cryotanks have been demonstrated to provide a 75% mass reduction compared to state of the art aerospace cryotanks (metal or composite). GTL has fabricated and tested multiple BHL Cryotanks at a range of scales, including an ultra-high performance 4 ft diameter by 8 ft long BHL composite liquid oxygen tank. BHL cryotanks have been demonstrated to be leak-tight even after repeated cryo-thermal pressure cycles. This technology has achieved TRL 6+ and is compatible with a variety of cryogenic propellants including liquid oxygen, liquid methane, and liquid hydrogen.

Structures & Materials

GTL has experience developing a wide variety of composite structures and advanced materials. In addition to conventional composite structures (graphite, fiberglass, etc.) for terrestrial applications, GTL has developed high-performance aerospace structures including ultralight space deployable booms, missile/rocket fins and nose cones, and truss structures. GTL’s structural nervous system technology integrates power and data networks into aerospace structures for control systems and health monitoring.

GTL’s materials research is developing materials for extreme environments, including cryogenic and high-temperature applications, along with high-radiation environments. This work is focused on incorporating new materials into manufacturing processes for polymer matrix, metal matrix, and ceramic matrix composite structures.
